CKD-EPI

Formula

Expressed as a single equation:

eGFR =
142^*
min(standardized S_cr/K, 1)^{α *}
max(standardized S_cr/K, 1)^{-1.200 *}
0.9938^{Age *}
1.012 [if female]

Abbreviations / Units

eGFR (estimated glomerular filtration rate) = mL/min/ 1.73 m²

S_cr (serum creatinine) = mg/dL

K = 0.7 (females) or 0.9 (males)

α = -0.241 (females) or -0.302 (males)

min = indicates the minimum of S_cr/K or 1

max = indicates the maximum of S_cr/K or 1
